Sharks get new protections at ICCAT

November 29, 2010 David Shiffman

Last week, the International Commission for the Conservation of Atlantic Tunas met in Paris. Among other responsibilities (such as the conservation of Atlantic tunas), ICCAT sets guidelines for several shark fisheries. My friend Sonja Fordham, President of Shark Advocates International, was there representing SAI. She is optimistic about a series of new shark conservation measures that the Commission adopted.

Grading President Obama on science and conservation

Earlier this week, Dr. M of Deep Sea News evaluated President Obama’s science and conservation policies and awarded him a B-. I gave President Obama a C+ overall after his first 100 days in office, noting that some things haven’t had enough time to be given a fair grade, and I think things have gotten much worse since then. I was a little shocked at how high this grade was, and I left Dr. M a snarky comment (sorry, Craig).

In the interest of fairness, I wanted to find a way to objectively grade these policies. The best that I can find is the Obameter, run by non-partisan fact checker Politifact. Basically, they record every promise that President Obama made during the campaign and since he’s become President, and they keep track of how each is progressing. Each is rated “promise kept”, “compromise” (something similar happened though not exactly what was promised), “in the works” (not done yet but actively being worked on), “stalled” (no work being done but it may happen at some point), and “promise broken”.

Shark News Roundup: the ecology of fear, curious whale sharks, and saving the manta rays

The shark blog-o-sphere has been busy lately. Here are some of the headlines from the world of shark science and conservation.

Chuck from Ya Like Dags has a fantastic post explaining the ecology of fear and how it relates to sharks. As it turns out, predators can have a major impact on an ecosystem just by being there- prey change their behavior in ecologically significant ways because they want to avoid being eaten. If you’re looking for scientific reasons why sharks are important to the ocean or if you’re just looking for a cool ecology story, check it out!

Al Dove of the Georgia Aquarium explains that whale sharks are curious animals that will sometimes swim over to check out humans. I’ve found that most sharks tend to avoid people, but he has a pretty convincing video.

Shades of Gray: Gray literature, peer-review, and the struggle for data in fisheries management

The dissemination of science follows the conventional route of rigorous peer-review followed by publication in an accredited scientific journal. This process has been the standard foundation from which the general public can trust that the science is, at the very least, valid and honest. Of course this system is not without its flaws. Scientific papers of questionable authority, dishonest methodology, or simply flawed design frequently make it through the gates of peer-review. Politically charged papers possess strong biases and many high impact journals favor sexy or controversial topics.

Beyond the conventional route of peer-review, there exist a vast accumulation of gray literature – conference reports, technical notes, institutional papers, various articles written for specific entities that enter into general circulation without the filter of peer-review. Much of gray literature is valid, robust science, but much of it is not. The challenge is that sometimes gray literature is the only science available.

The Gulf of Mexico Oil Spill: Day 209

In case anyone was under the impression that the Gulf of Mexico oil spill is over just because the well has been closed, it isn’t.

We continue to maintain our Gulf of Mexico Oilspill Page and will soon be adding a post-spill section to cover the ongoing effort in the Gulf.

An open letter about climate change to soon-to-be Speaker John Boehner

Dear Representative Boehner,

Congratulations on your party’s recent election victories. Your speech at the end of the night was particularly touching, and your personal story is inspirational. The election results do seem to signify that many Americans are not happy with how the Democratic party has been running Washington, and some change will likely be good for the country. As a scientist, however, I am deeply troubled by some of what I’m hearing about the new Republican House majority, particularly about global climate change policy.

Back from the Brink: Victories in Conservation

Earth is facing a biodiversity crisis so severe that many conservation scientists refer to it as a mass extinction event. The International Union for the Conservation of Nature (IUCN), a professional network of 11,000 volunteer scientists belonging to more than 1,000 government and NGO agencies in 160 countries, evaluates species worldwide and determines their risk of extinction. This Red List, which ranks species in increasing risk of extinction – Least Concern, Near Threatened, Conservation Dependent, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild, and Extinct – is described as “the world’s most comprehensive information source on the global conservation status of plant and animal species”.

Statistics from the Red List are terrifying. One fifth of all evaluated vertebrate species are threatened with extinction, including 12% of birds, 21% of mammals, 30% of amphibians, and 26% of fish. On average, fifty species of amphibians, birds, and mammals move measurably closer to extinction each year. One fifth of the world’s plant species are in danger of extinction. Critical habitat-builders, including 33% of reef building coral species and 14% of seagrass species are in very big trouble.

Save the krill!

The conservation movement is full of organizations whose stated goal is to protect specific organisms (i.e. “save the whales” or “save the sea turtles”) or to protect certain ecosystems (i.e. “save the rain forest” or “save the coral reef”). While these groups do admirable work, I can’t help put notice that they primarily focus on charismatic, likable organisms and ecosystems that are considered beautiful. The reason for this is simple- it’s easier to get the public to support conserving these things. Any conservation is a good thing, but when we focus exclusively on what we like instead of what’s important to the environment, it can lead to ecological disaster. That’s why I was so excited to learn of the existence of the “save the krill” movement.

Wait, stop – we have an Avatar tree too!

Remember how that Na'avi needed their tree of souls? Well, it might not be as obvious to us, but we depend on our forests too.

Dependence on natural resources is often relegated to a characteristic of the rural poor, a reason for development aid to swoop in and provide other economic opportunities. However, a recent article by Guo, Zhang, and Li in PLoS ONE has demonstrated that more developed countries actually have a higher dependence on ecosystem services. Basically, we may fire up our stoves with gas from eons ago rather than wood, but we’re even more dependent on that tree in the yard. We all laughed at the “primitive”, romanticized blue natives in Avatar, but their culture really wasn’t that different than ours.
